Key Features & Specifications:

Output: 12VDC @ 1200mA (1.2A maximum continuous output).
Input: Standard 120VAC.
DC Plug & Polarity: 2.5mm inner diameter x 5.5mm outer diameter barrel plug with strict center-positive (+) polarity.
Linear Design: A traditional linear power supply for compatible applications where a low-noise DC source is preferred.

Who May Need the PV-1212AP:

This specification may suit owners replacing a lost or worn supply for 12V audio equipment, electronics, and older gear that specifically calls for a 2.5mm x 5.5mm center-positive input. Customer use cases on this listing include Fosi Audio GR40 setups, older 12V car stereo equalizers used in home systems, DACs, and tube buffer preamps.

Typical Uses:

Home audio: Compatible DACs, preamps, headphone amplifiers, and small audio processors.
Vintage and car audio: Older 12V car stereo equalizers and similar equipment used in a home listening setup.
DIY and repair: Electronics projects, bench testing, and replacement-power-supply repairs when the equipment specifications match.

Important Compatibility Notes:

Before ordering, confirm that your device requires 12VDC, draws no more than 1200mA (1.2A), uses a 2.5mm x 5.5mm barrel jack, and specifies center-positive (+) polarity.
Do not substitute this supply for equipment using a 2.1mm plug, center-negative polarity, a different voltage, or a current requirement above 1.2A.
Plug dimensions and polarity must match exactly. Using the wrong power supply can damage your equipment.

AC-DC Linear Power Supply 12V DC @ 1200mA

Watched a power supply comparison on Old HiFi Guy's youtube channel.
I purchased 2 one for a Fosi Audio GR40 and the other for a Fiio K11 R2R.
The Fiio's switching power supply is 12 volt 2 amp so I did not try it with the Fiio.
Tried it with the Fosi GR40 on my modest near field system that is powered by a Fosi ZA3 amp with Sparko's opamp's, Sony SSCS 5 for mains and Polk Audio RM705 subwoofer.
The difference in sound stage, instrument placement, vocals and especially bass response was shocking. This PSP linear power supply made music like Stanley Clarkes School Day's, to stuff like Dave Brubeck's Time Out to the Who's Live at Leeds My Generation bass solo by John actually sound like a bass instrument instead of the expected performance of an inexpensive subwoofer.
Moving from a Douk Audio P1 tube preamp to the Fossi GR40 preamp/dac made a immediately noticeable improvement. This linear power supply gave a comparably obvious improvement to the overall sound.
Easily the best bang for the buck improvement to the overall sound I have ever purchased.

Top Notch Value

Bought this to replace the stock PS for my FX tube buffer pre-amp that I paid less than $30 brand new several years ago. Back then I replaced the Chinese tubes it came with for USA made GE tubes for around $28. I have a WiiM Ultra and Sony X800M 4k bdp that plays SACD, DVD-Audio(I have a collection of physical media). Both the Wiim(USB & optic) and the blue~ray player(digital coax) are linked to my Geshelli Labs J2S DAC with Sparkos op-amps. From there to a Schiit LYS(RCA switcher), 1 line going to the FX preamp then to my late model Sony ES AVR. I have EMF filtering on my surge protector, other quiet power supplies, ferrous chokes, etc, but nothing expensive. Anyway, now my system sounds better than ever. Subtle, yet beyond placebo to my ears. Perfect match for my use case. This PS is well constructed, allows my devise to achieve its potential, and it’s priced so low it doesn’t make sense not to try it. Satisfied customer, will shop AC-DC Powershack in the future. Oh btw, they shipped it immediately and it arrived in a couple days. Excellent service!

What an INCREDIBLE deal, what service!!! I'm be buying more!

I bought the Variac/isolation transformer combo. FOR STARTERS: NOBODY ELSE MAKES THIS COMBO with a genuine isolation transformer. And that fact that it's $200 out the door is insanity. My only advice with the unit would be to double check the voltage display against a multimeter; I find my display to be about 5V lower than the actual output and adjusted accordingly.

This item was packaged more securely than a nuclear warhead. Seriously, the packing job is a masterclass in transportation and logistical safeguards.

In short--I rarely leave reviews. I felt I HAD to for this product. If you're not sure because it's a newer item/company, don't worry. They are LEGIT and they are INCREDIBLE.
One more side note--customer service response is insanely fast also. I emailed a question on a SUNDAY EVENING and got an answer.

GREAT, domestically-owned small business I will support again.
